Introduction to the material properties of polyurethane

Polyurethane, also known as polyurethane, is a polymer. There are two types of polyurethane: polyester and polyether. They can be made of polyurethane plastics (primarily foam), polyurethane fibers, polyurethane rubber and elastomers.

Soft polyurethane mainly has a thermoplastic linear structure, which has better stability, chemical resistance, resilience and mechanical function than PVC foam data, and has less shrinkage and deformation. Good heat insulation, sound insulation, anti-vibration and anti-virus functions. Therefore, it can be used for packaging, sound insulation and filtering materials. Rigid polyurethane plastic has light weight, excellent sound and heat insulation performance, chemical resistance, good electrical performance, easy processing, and low water absorption. It is mainly used for structural data such as construction, cars, aviation industry, and thermal insulation. The function of polyurethane elastomer is between plastic and rubber, oil resistance, abrasion resistance, low temperature resistance, aging resistance, high hardness and elasticity. Mainly used in shoemaking occupations and medical occupations. Polyurethane can also be used to make adhesives, coatings, synthetic leather, etc. Polyurethane elastic washers

my country's polyurethane industry is mainly concentrated in the Yangtze River Delta region. In recent years, with the continuous development of industrial production technology, the Bohai Rim production area, the Pearl River Delta production area and the Northwest production industrial base centered on Yantai are all booming. Under the pressure of domestic environmental protection, various enterprises have begun to seek transformation, with the primary development direction of creating a green and environmentally friendly polyurethane production process, and gradually screening outdated production capacity. It is estimated that in the next few years, my country's polyurethane products will be mainly used in construction, furniture and sports.
